Default Rocket Rally custom GT2871r Rotated Turbo (stage1, stage 2 comparison)

Thanks to the guys at Rocket Rally. Was getting to used to my Stage 2 setup called up Pat and Onur decided on a RR custom rotated GT2871r setup.

Been driving the car now for 3months and it puts a smile on my face everytime. Perfect setup for a daily driver with instant spool and lots of down low torque but pulls hard enough up top for the occasional trackday.

Facility: www.rocketrally.com
Type of Dyno: Dyno Dynamics
Baseline # for a stocker at the dyno: around 208whp
Boost: 20psi
Fuel: 94 Octane
Target AFR: Unknown
SAE Corrections: Unknown
Mods:
GT2871R
750CC Top Feed
AVO Fuel Pump
Rotated setup with custom up-pipe, DP, intake, EWG setup, heat wrapped
catless downpipe
magna flow exhaust

My Car has been tuned from day 1 with Rocket Rally with (500kms on the ODO) 3yrs and 50,000km later it's still running strong. Pat and Onur has always been awesome with fixing or answering any issues I have with my car. Can't say enough about Rocket's customer support.

Here are my car's numbers at various stages on Rocket's Dyno:
Stock: 210whp
Stage 2: 240whp
Rotated GT28r: 320whp

RR Protune Stage 2 vs stock

RR Rotated GT28r setup

looks like a really fun setup. I always wanted to see a gt28r setup on one of these cars but everyone always says too small. I know they'll make more power than a vf39. Not a buttload more but I would be willing to bet spool is just about identical to stock. I suppose the biggest factor to why people don't do it is because of the cost vs. how much you really get out of it.

54% more whp from stock and 32% from stage 2 and a torque/hp curve that does look like a downhill ski slope. been driving this setup for 3month now I'm convinced that my tuner pick the right setup. Awesome setup for a DD and perfect for people who don't want to mess with the stock internals.

I had trouble finding any STI on the web with this setup but my tuner was convinced this was right turbo for my needs. Just wanted to share this setup with people who are looking for a smaller quick spooling turbo setup.

Cool setup. I was wondering what type of power a GT28 would make on our engines. Probably a good choice for the injectors / current fuel setup as they shouldn't be pegged with some extra room to play with.

What color is your STi? I am from B.C. as well so I am wondering if I have ever bumped into you on the track. I have seen a few white, silver 08+ STi's at Mission Raceway.

See ya around. - R.T.

That guy was probably me...

That was the main issue with me.. wanted a reliable daily driver that I can take to the track and pound on it all day long without worrying about my motor blowing up.

Yah.. since it is a daily driver we didn't want to overkill with the injectors and have it idle rough. All in all i'm pretty happy with the current setup. I've done mission twice... most of our trackdays are done at Portland.

White with gold bbs for street or black ultraleggera on the track

pretty nice turn out. You seemed to have lost none of the low end power (peak tq at 3500 or so) and doesn't drop off nearly as quickly.

I think that stock tmic is ok for that bhp.
I would put a turbo blanket on that turbo though

So you would recommend this setup? I have my rotated kit laying around here and am trying to decide between installing it and selling it. Has 7-8k on it if anyone is interested.

I'm sure that car is capable of hitting 400 whp on meth or ethanol, engine bay looks very clean btw.

that's what I want mine to look like but with a 5857

Nice setup. The STI TMIC is much more capable then most think. The 08+ sti tmic is like a factory spearco. "or as close to a spearco from the factory lol" It has alot more to do with keeping turbo in its efficiency range.

That is a hell of a setup! I'm really surprised how much power your making at such a low rpm. BTW, I hate you for having 94 octane available, I can't get anything but 91. Of course, that's why I run E85, but still

I wanted to get a FMIC or at least a bigger Top mount. My tuner say no need for this setup.

for those power levels the GR STI tmic is the biggest and even the older ones are capable of holding some good numbers.

Wow.. Good #'s for 20 psi on pump / stock tmic... It looks shockingly like the shape of my 68hta on my 2.0 on e85 @ 21psi - except you had a couple hundred RPM better spool. I'm curious to see what would happen with more boost and better fuel.

GT2871 is the disco potato turbo yeah? Or is that the GT2876RS? In any case, I considered this turbo for my 2.0 as a DD/stock replacement. Glad to see that the numbers are there to support my decision/research.

^ Disco Potato is the GT2860RS.


Which trim of GT2871R is this? There are three different trims of that compressor. 48, 52, and 56 trim. Also, what turbine housing?


I used to have a 56 trim version with the .86 exhaust housing on my 22T. It was a great combo.

Im interested in the same info. Looking for a new CHRA GT2871R, going to use my existing GT2560 0.64 A/R exhaust housing. Trying to pick the right compressor though! Support 400, 440, or 475 HP!
